01GA611, Castle

Most Measurement codes of practice and legislative guides demand that an independent acoustic calibration of any sound level meter should be made before and after a series of measurements and the Castle dBCal Calibrators provide just that facility. They all produce a calibration tone of 1kHz at levels of 94dB, 104dB or 114dB at the microphone. They are designed to fit standard 1/2 microphones. These calibrators fully comply with IEC60942:2018 3 output Levels – 94dB, 104dB and 114dB Fully compliant with IEC60942:2018 Output frequency of 1KHz Temperature and pressure compensated Simple operation Compatible with Castle auto-cal feature Tough ABS plastic case Works on 2 x AA batteries 70-hour battery life. cavity diameter The dBCal (GA611) is a class 1 product according to IEC60942:2018, with a tolerance of +/- 0.25dB and distortion of less than 1%. Class 1 to IEC60942:2018 Less than 1% harmonic distortion Pluss or minus 0.25dB tolerance

CEL-120/2, Casella Cel

CEL-120 Class 2 Acoustic Calibrator The CEL-120/2 is a Class 2 accuracy Acoustic Calibrator and is the smallest of its type in the world; with a rugged, over-moulded design for use in field environments. The field calibration of sound level meters is an essential procedure when carrying out any type of noise survey both before and after each measurement sequence. This ensures that sound level measuring instruments are providing consistently accurate readings necessary for monitoring to ensure compliance with workplace and environmental noise regulations. The CEL-120/2 is therefore designed and manufactured to comply with the requirements of IEC 60942: 2003 and ANSI S1.40: 2006. These standards stipulate accurate calibration over a wide range of temperature, humidity and pressure conditions, typical of field work, ensuring accurate calibration in all conditions. Standards IEC 6094: 2003 and ANSI S1.40: 2006
